202 CAPRIFOLIACE^E. (HONEYSUCKLE FAMILY.) 



Division II. MONOPETALOUS EXOGENOUS PLANTS. 



Floral envelopes consisting of both calyx and corolla, the latter 

 composed of more or less united petals, that is, monopetalous.* 



Order 49. CAPRIFOLJACEtE. (Honeysuckle Family.) 



Shrubs, or rarely herbs, with opposite leaves, no {genuine) stipules, the 

 calyx-tube coherent with the 2 - 5-celled ovary, the stamens as many as (of 

 one fewer than) the lobes of the tubular or wheel-shaped corolla, and inserted 

 on its tube. — Fruit a berry, drupe, or pod, 1 - several-seeded. Seeds an- 

 atropous, with a small embryo in fleshy albumen. 



Tribe I. IiONICEREJE. Corolla tubular, often Irregular, sometimes 2-lipped. Style 

 slender : stigma capitate. 



1. Liimrea. Stamens 4, one fewer than the lobes of the corolla. Fruit dry, 3-celled, but only 



1-seeded ; two of the cells sterile. 



2. Sympb.orica.rpus. Stamens 4 or 5, as many as the lobes of the bell-shaped regular 



corolla. Berry 4-celled, but only 2-seeded ; two of the cells sterile. 



3. Lionicera. Stamens 5, as many as the lobes of the tubular and more or less irregular 



corolla. Berry several-seeded ; all the 2 or 3 cells fertile. 



4. Diervilla. Stamens 5. Corolla funnel-form, nearly regular. Pod 2-celled, 2-valved, 



many-seeded, slender. 



5. Triosteum. Stamens 5. Corolla gibbous at the base. Fruit a 3-celled drupe. 



Tribe II. SAMBUCEJE. Coralla wheel-shaped or urn-shaped, regular, deeply 5-lobed. 

 Stigmas 1-3, rarely 5, sessile. Flowers in broad cymes. 



6. Sambucus. Fruit berry-like containing the small seed-like nutlets. Leaves pinnate. 



7. Viburnum. Fruit a 1-celled 1-seeded drupe, with a compressed stone. Leaves simple. 



1 . LINN JE A , Grouov. Linn^a. Twin-flower. 



Calyx-teeth 5, awl-shaped, deciduous. Corolla narrow bell-shaped, almost 

 equally 5-lobed. Stamens 4, two of them shorter, inserted toward the base of 

 the corolla. Ovary and the small dry pod 3-celled, but only 1 seeded, two of the 

 cells having only abortive ovules. — A slender creeping and trailing little ever- 

 green, somewhat hairy, with rounded-oval sparingly crenate leaves contracted at 

 the base into short petioles, and thread-like upright peduncles forking into 2 

 pedicels at (he top, each bearing a delicate and fragrant nodding flower. Co- 

 rolla purple and whitish, hairy inside. (Dedicated to the immortal Linncens, 

 who first pointed out its characters, and Avith whom this pretty little plant was a 

 special favorite.) 



1. L. borealis, Gronov. — Moist mossy woods and cold bogs: common 

 northward, but towards the south of rare occurrence as far as New Jersey, and 

 along the mountains to Maryland. June. (Eu.) 



* In certain families, such as Ericaceae, &c, the petals in some genera are nearly or quite sep- 

 arate. In Compositse and some others, the calyx is mostly reduced to a pappus, or to scales, or a 

 mere border, or even to nothing more than a covering of the surface of the ovary. The student 

 might look for these in the first or the third division. But the artificial analysis prefixed to the 

 volume provides for such anomalies, and will lead the student to the proper order.
